I've just entered the factors into FactorDB.

3270.698 linear algebra started
 

Should take until September 1 (452 hours estimate) for 23.9M density-120 matrix (8 cores Xeon D1540)

190-digit GNFS seems to be about the point where the linear algebra on one fast machine and the 15e sieving on NFS@home take equal time - according to my logs, the sieving has taken about 24 days and the linalg will take 19 days. I just about have enough fast machines to keep up.

For comparison, C193_2340_742 averaged 19.2M relations per day, and sieved 435M relations, so that's 23 days of sieving and the linear algebra ETA was 650 hours = 27 days.

I'll take 10321_61_minus1 when it finishes sieving.

I'll take C177_123_92, once sieving is complete. Thanks.

I'll take 10739_61_minus1 next.

C193_2340_742 done

About 654 hours on six cores i7/4930K for a 31.47M matrix at density 120. Log attached.

Linear algebra started on C182_147_125; it'll finish quickly but I'll be on vacation and probably unable to read out the answer until 1 September. Equally I won't be able to start post-processing on new numbers, so it would be nice if someone else with a quad-core and 16G memory took them as they come due.

10321_61_minus1 factored
 

Took 64 hours to solve a 9.4M matrix on a Core-i5 -t 4 with TD=124.
